Abstract
The utility model relates to a machine for cutting stalks and ploughing stubbles, comprising a crank link mechanism, a rectangular knife blade, a knife handle guide device and a press roll, wherein, the rectangular knife blade is arranged below a connecting rod, and a knife handle arranged on both ends of the rectangular knife blade is inserted to the knife handle guide device arranged on both sides of a machine frame. The press roll is arranged below the machine frame and is positioned in front of the rectangular knife blade. The machine for cutting stalks and ploughing stubbles uses a 12 horse-power tractor as matching motive power, and the stalk cutting and stubble ploughing is realized by the up and down reciprocating motion of the rectangular knife blade. The utility model has the advantages of simple structure, small matching motive power, and short stalks after cutting. Meantime, the utility model can cut root stubbles into pieces, and the stalks are dispersed homogeneously.
Description
The utility model relates to a kind of stalk cutting stubble cleaner, belongs to agricultural machinery.
The present straw cutting apparatus that uses, mostly be to utilize the blade of high speed rotating that stalk is cut down from root, inspection is picked up, pass through feeding mouth, squeeze in the cylinder after the chopping continuously by moving knife and stationary knife, through the repeatedly action of a series of complexity such as impact cutting, bump, pulverizing, friction, gentle stranding, dish out from the cylinder rear exit at last again.The shortcoming of this return straw into soil machine is: the first, can not stubble-cleaning, and the stalk after the cutting spreads inhomogeneously.The second, the stalk after the pulverizing is longer.The 3rd, mating power is big, generally more than 55 horsepowers.
The purpose of this utility model is the shortcoming at above-mentioned prior art, and provides a kind of simple in structure, and the straw after the cutting is short, and can shred root stubble and the uniform stalk stubble cleaner of spreading simultaneously.
The utility model is realized in the following manner: it is by toggle, rectangular blade, and handle of a knife guider and nip drum are formed.Rectangular blade is installed in the below of connecting rod, and the handle of a knife at rectangular blade two ends inserts the handle of a knife guider that is arranged in the frame both sides respectively, and nip drum is installed in the below of frame and is positioned at the place ahead of rectangular blade.Its power is outer power.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a profile front view of the present utility model (schematic diagram)
Fig. 3 is vertical view of the present utility model (schematic diagram)
Among the figure, 1, shell, 2, bent axle, 3, handle of a knife, 4, connecting rod, 5, rectangular blade, 6, directive wheel, 7, belt pulley, 8, nip drum, 9, bearing cap, 10, the straw guiding fork, 11, the nip drum pedestal, 12, balancing weight.
In Fig. 1, toggle is made up of crank 2, connecting rod 4, belt pulley 7, and balancing weight 12 is housed on the bent axle 2.Rectangular blade 5 is installed in the below of connecting rod 4, and its connecting mode adopts the movable connection of bearing pin.Connecting rod 4 can make the version that length can be regulated, to regulate the embedded depth of blade.
At rectangular blade 5 two ends handle of a knife 3 is housed, handle of a knife 3 inserts the handle of a knife guider that is arranged in the frame both sides respectively, and in the present embodiment, the handle of a knife guider is made up of the two row's directive wheels 6 that are positioned at the frame both sides.Two row's directive wheels have an inclination angle when blade 5 is buried.The handle of a knife guider also can adopt the version of gathering sill.
In order to be beneficial to the cutting stalk, below frame, nip drum 8 is housed with the place ahead of rectangular blade, nip drum 8 is contained on the frame by nip drum pedestal 11.Nip drum plays support, walking and push down the effect of stalk down when cutting.
In the front lower place of frame straw guiding fork 10 is housed, guiding fork 10 is formed it by two cuboid pieces enters under the nip drum 8 straw smoothly.
Operation principle of the present utility model is as follows: it is a mating power with 12 horsepowers of tractors, and the mode of articulating adopts rearmounted integral, by belt transmission, makes belt pulley 7 rotations, drives toggle, makes rotation fortune become the rectilinear motion up and down of connecting rod.Stalk enters the body below through guiding fork, is overwhelmed, flattens by nip drum, and the blade that is installed in the connecting rod lower end pumps with connecting rod.And blade moves downward and can enter about the interior 70mm of soil, therefore
Stalk is all together shredded by blade together with the root stubble in the ground of nuzzling.The number of times that blade pumps is about 2000 times/minute, and stalk and root stubble are 25-30mm by the length after pulverizing, and operating speed is generally 4-6 kilometer/hour.
The utility model has the advantages that simple in structurely, volume is little, and is in light weight, and supporting power is little, and the straw after the cutting is short, can shred root stubble and weeds simultaneously, and stalk scatters evenly. Cutting, stubble-cleaning is disposable finishes.
Claims (4)
1, a kind of stalk cutting stubble cleaner that drives by outer power, it is characterized in that it is made up of toggle, rectangular blade, handle of a knife guider, nip drum, rectangular blade is installed in the below of connecting rod, the handle of a knife at rectangular blade two ends inserts the handle of a knife that is arranged in the frame both sides respectively to device, and nip drum is installed in the below of frame and is positioned at the place ahead of rectangular blade.
2, straw according to claim 1 cutting stubble cleaner is characterized in that toggle is made up of bent axle, connecting rod, belt pulley, and balancing weight is housed on the bent axle.
3, stalk cutting stubble cleaner according to claim 2 is characterized in that being made up of the two row's directive wheels that are positioned at the frame both sides on the handle of a knife guider.
4, stalk cutting stubble cleaner according to claim 2 is characterized in that in the front lower place of frame the straw guiding fork being housed.
